I. Question/Purpose: What do I want to determine from this experiment? (10 pts.)

II. Prior Knowledge: What did/do I already know about the topic that is relevant to this lab? (5 pts.)

III. Hypothesis: Your prediction as to what will happen based upon your prior knowledge and what you have observed. Be sure that it is valid (testable). (10 pts.)

IV. Variables: List all of your variables here. (10 pts.) a. Manipulated/Independent: What you are changing/controlling b. Responding /Dependent: What you are measuring c. Controlled: All of the factors that must remain constant

V. Materials: List the items that you used during the experiment. Don’t leave anything out. (5 pts.) VI. Step-By-Step Procedure: Write this so that anybody who reads your procedure can do your experiment without have to ask you any questions. (5 pts.) VII. Data: Insert your data table, here. (20 pts. For All Data and Graphs) VIII. Graphs: If your lab includes any graphs…this is where they go. Be sure to use graph paper and a ruler or computer generated graphs. Your graph(s) should be titled, labeled, and include units. Also be sure to use the appropriate type of graph (line, bar, etc.). (see data) IX. Conclusion:

Lab Conclusion……. First Paragraph: In this lab we studied whether giving a rye grass plant______would affect the rate at which rye grass grows. To do this we grew two rye grass plants, one as a control and the other plant was placed in the environment with______. We measured and analyzed the data to determine ______Second Paragraph: My hypothesis was______My analysis of the data supported/refuted this hypothesis. During the course of the first two data points, control plant/experimental plant exhibited the greatest mean growth at ___cm. ______showed slower growth, at ___. On (date) (the third data point), the ______plant had grown enough to overtake ______plant and by the end of the experiment, ______plant had shown the greatest growth. By the end of the experiment the control plant and the experimental plant exhibited several qualitative observations. The control plant grass was fanning out and growing away from each other and darker green in appearance. The experimental (no light) was growing straight up and had a yellowish – light green appearance.

Third Paragraph: By observing and measuring growth of rye grass plant in a different environment, we were able to determine that ______does affect growth. A real-world connection: discuss who would find this knowledge useful. Extension: what is another experiment that you could do to learn more? (30pts)

X. Possible Sources of Error: Discuss anything that might have interfered with your experiment. Explain how these impacted the outcome and what changes could be made in future experiments (5 pts.)
